Trait Implementations

impl Clone for Kyber256Params

fn clone(&self) -> Kyber256Params

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Kyber256Params

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Modulus for Kyber256Params

const Q: u32 = 3_329u32

The primary modulus Q for coefficient arithmetic

const N: usize = 256usize

The polynomial degree N (number of coefficients)

const BARRETT_MU: u128 = 10_569_051_393u128

Barrett reduction constant mu = floor(2^k / Q) Set to 0 for dynamic computation

const BARRETT_K: u32 = 45u32

Barrett reduction shift amount k Set to 0 for dynamic computation

impl NttModulus for Kyber256Params

const N_INV: u32 = 2_385u32

(256⁻¹) in Montgomery form: (256⁻¹ · R₃₂) mod Q

const MONT_R: u32 = 1_353u32

2³² mod Q

const NEG_QINV: u32 = 2_488_732_927u32

-Q⁻¹ mod 2³² (0x94570CFF)

const ZETA: u32 = 17u32

Primitive root of unity (generator)

const ZETAS: &'static [u32]

Precomputed twiddle factors for forward NTT CRITICAL: For Dilithium, these are stored in MONTGOMERY domain (ζ·R mod q) exactly as in the FIPS-204 reference implementation. Do NOT convert them again - that would give ζ·R² mod q!

const PSIS: &'static [u32]

Twist factors ψ_i = ω^(bitrev(i)) in STANDARD domain (length N) These are the N-th roots of the primitive 2N-th root of unity Required for twisted/negacyclic NTT (Dilithium) NOTE: FIPS-204 reference implementation does NOT use these!

const INV_PSIS: &'static [u32]

Inverse twist factors ψ_i^(-1) in STANDARD domain (length N) Required for inverse twisted/negacyclic NTT (Dilithium) NOTE: FIPS-204 reference implementation does NOT use these!

const POST_INVNTT_MODE: PostInvNtt = PostInvNtt::Standard

How the coefficients should be post-processed after the inverse NTT.
